Ducks Unlimited is a conservation group that has been around for nearly 80 years. Duckbills Unlimited is arguably a lot older than that! Hadrosaurs (the "duckbilled" dinosaurs) lived for millions of years during the Cretaceous Period. Show your support for the famed duckbilled dinosaurs with this parody bumpersticker reminisent of the Ducks Unlimited logo. This sticker features a Corythosaurus head and is ready to be placed on a car window or other dark surface! This design is printed only in white ink on a clear sticker.
